Momentum-Dependent Hybridization Gap and dispersive in-gap state of The Kondo Semiconductor SmB6
We report the temperature-dependent three-dimensional angle-resolved
photoemission spectra of the Kondo semiconductor SmB. We found a difference
in the temperature dependence of the peaks at the X and points, due to
hybridization between the Sm 5d conduction band and the nearly localized Sm 4f
state. The peak intensity at the X point has the same temperature dependence as
the valence transition below 120 K, while that at the point is
consistent with the magnetic excitation at Q=(0.5,0.5,0.5) below 30 K. This
suggests that the hybridization with the valence transition mainly occurs at
the X point, and the initial state of the magnetic excitation is located at the
point.Comment: 5 pages, 3 figure
How and What in Education
教育現場を始め、教育方法を巡っての議論は古今絶えないが、教育方法の背後にはそれを支持する教育哲学があるという指摘が教育哲学者村井実より提議された。本論は「教育における方法と哲学の関係」と題し、中国海南師範大学で行った講演を加筆したものである
RELATION BETWEEN RELEASE PARAMETERS AND THROWING DISTANCE OF THE JAVELIN THROW
The present study was clarified a three-dimensional examination of the relation between the release parameters and throwing distances, in order to understand the initial flight characteristics of javelins. The subjects were 57 right-handed javelin throwers. The measured throwing distances ranged from 45.25 m to 87.17 m. The elite throwers had tendency to significant positive correlation between theoretical distance and initial velocity of javelin release. Throwers who achieved throwing distances of over 70m were observed to have throwing distances that were shorter than their theoretical distances, while those whose throwing distances were under 70 m group had throwing distances that were longer than their theoretical distances. When the data were applied to initial velocity of javelin release, it was equivalent to 26 m/s
From Mott insulator to ferromagnetic metal: a pressure study of CaRuO
We show that the pressure-temperature phase diagram of the Mott insulator
CaRuO features a metal-insulator transition at 0.5GPa: at 300K from
paramagnetic insulator to paramagnetic quasi-two-dimensional metal; at
12K from antiferromagnetic insulator to ferromagnetic, highly anisotropic,
three-dimensional metal. % We compare the metallic state to that of the
structurally related p-wave superconductor SrRuO, and discuss the
importance of structural distortions, which are expected to couple strongly to
pressure.Comment: 4 pages, 4figure
